Description
This function searches for a given color specified by Color within a tolerance range specified by Tol inside of a given circular search area specified by the midpoint (mx, my) and the radius r which is specified relative to the selected client window. The function returns false if the color was not found, if it was it returns true and the coordinates of the found color in (x, y). The search will stop after the first color was found. The active tolerance algorithm can be changed using the ColorToleranceSpeed function.
Example
var
w, h: Integer;
x, y: Integer;
begin
GetClientDimensions(w, h);
if FindColorCircleTolerance(x, y, 4, w div 2, h div 2, w div 4, 5) then
WriteLn('Found color at ' + IntToStr(x) + ', ' + IntToStr(y));
end.
